Just to clarify, at 7:00, the video incorrectly suggests that you can permanently destroy your own pieces. From page 6 of the rules: “In addition to removing the 4 pieces, the pieces that form a direct extension of these 4 pieces must also be removed. The pieces of the player’s own color are returned to his reserve and the pieces of the other color are captured, thus lost for the opponent.”
